# repos_get_branch_protection

> Read a branch's protection rules — required checks, required reviews, linear history — before attempting a write that they would refuse. A 404 means either no such branch or no protection on it; GitHub does not distinguish them.

<div className="tool-route"><span className="tool-row-method" data-method="GET">GET</span><code>{"https://api.github.com/repos/{owner}/{repo}/branches/{branch}/protection"}</code></div>

```python github_repos_get_branch_protection.py theme={null}
from charter.packs import github

result = await github.repos_get_branch_protection.ainvoke({"owner": ..., "repo": ..., "branch": ...})
```

<Note>
  Requires `repo`, `read:user`.
